Definition • Epistemology is the theory of knowledge. • It asks what is the origin of knowledge? What can we know and how do we know it? • It examines experience and reason as generating knowledge. • It examines certainty and skepticism.
Descartes • Skepticism • Malignant Demon • Cogito, ergo sum • Dualism
Two Schools of Thought • Rationalists and Empiricists • Rationalists: • Descartes and Spinoza • Experience is unreliable and information derived from it is uncertain. • The starting point for all knowledge is reason. • A priori concepts (those that exist in the mind at birth) are self-evident. Such concepts include space and time; cause and effect. Mathematical truths are discovered, but exist already in the mind.
Empiricists: • Hume and Locke • Experience is unreliable and information derived from it is uncertain. • Sense experience and perception are the starting point for all knowledge. • We can never be certain. • Hume advocated a “mitigated skepticism” • Hume and Locke advocate tolerance http://upload.wikimedia.org/wikipedia/commons/1/1c/Allan_Ramsay_-_David_Hume,_1711_-_1776._Historian_and_philosopher_-_Google_Art_Project.jpg; ; http://raymondpronk.files.wordpress.com/2012/01/john-locke-portrait.jpg
